BALING- SPECIFICATION forming part of Letters Patent No. 750,232, datedJanuary 19, 1904.

Application filed June 15, 1903.

To all whom it may concern.-

Be it known that I, ERNEST D. SMITH, a citizen of the United States,residing at Lockhart, i in the county of Caldwell and State of Texas,have invented a new and useful Baling-Press,

This invention relates to certain improve-; ments in hay-presses, andhas for its principal object to provide a simple, economical, andpowerful form' of press for the condens ing of hay and other materialsinto the form of bales or bundles.

One object of the invention is to provide a device of this character inwhich a system of toggle-levers is so connected to the pressplunger thatthe necessary compressing force may be obtained from a single animalwithout unnecessary strain on the animal or on any of the parts of theapparatus.

A further object of the invention is to construct a plunger operatingmechanism in which the horse-power, preferably of sweeplike form,elfects the operation of the plunger twice during each-rotation of thesweep and in which provision is made for automatically disengaging thehorse-power from the plunger-operating levers as soon as the latter havereached the full limit of the compressionstroke.

A still further object of the invention is to provide a device of thischaracter in which the compression-levers are positively returned to aninitial position and the plunger positively withdrawn to the limit ofits outstroke by automatic engagement of the horse-power with saidlevers.

With these and other objects in View, as will hereinafter more fullyappear, the inven- A tion consists in the novel construction andarrangement of parts, hereinafter described, illustrated in theaccompanying drawings, and particularly pointed out in the appendedclaims, it being. understood that various changes in the form,proportions, size, and minor details of the structure may be madewithout departing from the spirit or sacrificing any of the advantagesof the invention.

,In the accompanying drawings, Figure 1 is a plan View of a hay-pressconstructed in ac- Serial No. 161,570. (No model.)

cordance with the invention and illustrating the plunger at the limit ofits outstroke. Fig. 2 is a similar view showing the plunger at the limitof its compression-stroke; Figs. 3 and 4 are detail views morespecifically referred 9 to hereinafter.

. Similar numerals of reference are employed to indicate correspondingparts throughout the several figures of the drawings.

In the drawings, 1 indicates the compression chamber or box, which maybe of the usual construction and provided with a plum also provided withrecesses 8, each recess receiving a projecting portion of one of theadjacent frame members in order to prevent their longitudinal separationduring the operation of the press, while permitting ready detachment ofthe powerhead and horsepower from the compression-chamber in order thatthe two members may be conveniently loaded on a Wagon or truck fortransportation. The two sills 3 are connected together at anintermediate point by cross bars or planks 9 and 10, which serve tosupport the pivot-pin of the power-head, while the bar or plank 10 isextended for a considerable distance on each side of the sills, and itsupper face is covered in part with iron sheathing to form a suitablerest and support for a portion of the toggle mechanism.

The two main levers 12 and 13 of the toggle are connected, respectively,to the plunger 2, and the pivot-pin'5, and said levers are pivotallyconnected to each other by a pin or stud 14, on which is also hung theintermediate bar 15, which connects the toggle to the horsepower, andlongitudinalmovement imparted to this intermediate bar 15 in onedirection will tend to move the plunger inwardly into the press-box toeflect the compression-stroke, while the movement in the oppositedirection tends to withdraw the plunger and return the toggle-levers toan initial position.

The horse-power comprises a horizontallydisposed bar 16, pivoted at acentral point on the pin or stud 11 and furnished with twoangularly-disposed sweep-arms 17, which at their outer ends areconnected together and serve to support a swingletree 18, to which theanimal may be harnessed. Near each end of the bar 16 are depending pinsor lugs 19, which when in proper position engage alternately with a hook20, carried by the inner end of the bar 16, and said hook is at alltimes held in proper position to be engaged by the pins by means of asuitable tension spring 21, connecting the outer portion of bar 15 withone of the togglelevers 12. In the operation of this portion of themechanism the rotative movement of the sweep will bring one of the pins19 into engagement with the hook 20, and as rotative movement iscontinued the toggle-levers will be drawn to the position shown in Fig.2, being nearly or quite in alinement with each other and exertingconsiderable force on the plunger to compress the material previouslyinserted in the press-box. As the parts approach the limits of eflectivemovement the pin will tend to separate from the hook, and to permit thismovement the hook is provided with a bill extending practically at aright angle to the length of the bar 15, so that the pin may slidefreely from said hook. To insure the positive disengagement of the pinfrom the hook and the return of the toggle-levers to initial position,as well as to prevent the sweep from coming into contact with the legsof the animal, I employ apair of pivoted arms 24 and 25, one of which ispivoted to one of the sills 3, while the other is pivotally connected tothe toggle-lever 13. These two bars are pivotally connected at theirouter ends, and projected from the end portion thereof is a finger 26,which at the limit of compression movement is disposed in the path ofbar 15, contact of the bar 15 with said linger serving to positivelydisengage the hook. As soon as this is accomplished the bar 16 engages afinger 27, also disposed at the outer ends of arms 24: and 25, androtative movement of the bar 16 is then trans mitted through arm 25 andtends to force the toggle-levers to return to initial position. Thisengagement of the parts prevents any sudden movement of the sweep whenthe hook is disengaged from the pin and prevents contact of the sweepwith the legs of the animal. The arrangement of the arm 24 is such as togradually disengage finger 27 from the bar 16, so that it will beimpossible to break or strain any of the parts.

The spring 21 is employed to hold the bar 15 in such position that itshook shall at all times be in readiness to be engaged by one of the pins19.

The length of the toggle-levers is such as to render it unnecessary toemploy very heavy or expensive arms or connections, while the movementof all of the parts is positive in its character and the levers are soproportioned that great pressure may be exerted without undue strain onthe animal.

Having thus described the invention, what is claimed is 1. Thecombination in a baling-press, of a compression-box and plunger, asystem of toggle-levers connected to the plunger and including anintermediate operatingbar, a horse-power, means for connecting thehorsepower to the intermediate bar, and means carried in part by thetoggle mechanism for positively disengaging such connecting means at thelimit of the compression-stroke.

2. The combination in a baling-press, of a compression-box and plunger,a system of toggle-levers operatively connected to the plunger andincluding an intermediate bar, a hook member carried by said bar, arevoluble horsepower including a pivotally-mounted bar, pins carried bythe opposite end portions of said pivotally-mounted bar and adapted toengage the hook member, means operable in part by the toggle mechanismfor positively disengaging the hook at the limit-of eachcompression-stroke.

3. The combination in a baling-press, of a compression-box and plunger,a system of toggle-levers operatively connected to the plunger, ahorse-power, means for connecting the horse-power to the togglemechanism, a pair of bars pivotally connected at one end and at theiropposite ends connected respectively to a fixed point and to one of thetoggle-levers, the pivotally-connected ends or said bars being movedduring the compression-stroke to a position to effect the disengagementof the means for connecting the horse-power and toggle mechanism.

4. The combination in a baling-press, of a compression-box and plunger,a system of toggle-levers operatively connected to the plunger, ahorse-power, means for connecting the same to the toggle mechanism,means for disconnecting the toggle mechanism and horsepower at the limitof the compression-stroke, consisting of a pair of pivotally-connectedbars of which one is connected to one of the toggle-levers, theconnected ends of the bars being disposed in the path of movement of thehorse-power.

5. The combination with a baling-press including a compression-box andplunger, of a toggle mechanism operatively connected to the plunger andincluding an intermediate bar, a revoluble sweep, a pin or lug carriedby a portion of the sweep, a hook member carried by the intermediate barof the toggle and adapted to be engaged by the pin or lug, a pair ofpivotally-connected bars of which one is pivoted to a fixed point andthe other to one of the toggle-levers, and a pair of fingers carried bysaid bars and disposed one in the path of movement of the hook and theother in the path of movement of the sweep. said fingers servingrespectively to release the hook and 10 to operatively connect thetoggle mechanism to the horse-power and return the parts to initialposition.

In testimony that I claim the foregoing as my own I have hereto afiixedmy signature in the presence of two Witnesses.
